MEANS FOR SUPPORTING THE BOLT-WORK 0F SAFES AND VAULTS.

SPECIFICATION forming part of Letters Patent No. 296,867, dated April15, 188%.

i Application filed April 24, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY F. NEWBURY, of Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Safes and Vaults, (Case Y and I hereby declare that thefollowing is a full, clear, and exactdescription of one division of myinvention, and will onable others skilled in the art to make, construct,and use the same.

The bolt-frames of the doors of burglarproof safes are-necessarily madestrong and massive. Moreover, they are bolted rigidly to the inner faceof the door. If they were secured to the door by flexible connections,allowing a movement of the bolt-frame relatively to the door, therewould be danger that the door might be wedged open, or opened far enoughto admit of the introduction of powder or similar explosives. It resultsthat if a charge of dynamite or other similar material be explodedagainst the exterior of the door, the bolt-frame can be made to take ongreat momentum, and by a succession of such ex plosions properlydirected, there is a danger that the fastening-bolts of the bolt-framemay be broken, and the bolt-frame itself detached from the door. Thiswould leave the door in condition to be opened.

The object of the present invention is to provide means to prevent suchdisplacement of the bolt-framc; and it consists in providing abutmentsfor arresting the inward movement of the door and bolt-frame whensubjected to a sudden and heavy shock of the nature indicated.

The invention is fully illustrated in the accompanying drawings, inwhich Figure 1 is a horizontal section of a safe, showing oneconstruction of supporting abutinents arranged behind the bolt-fraine ofthe door. A is the safedoor, to which the bolt-frame B B, carrying thebolts (3, is rigidly secured by ordinary screw-bolts. D D are abutmentsarranged behind the boltbars-TB B, andin such relation to them that whenthesafe-door is closed they will be in contact, or nearly so, with theabutments. The abutment D is shown as bolted directly to the side wallof the safe, being at the same time long enough to rest against the rearwall thereof; The other abutment, D, is supported upon the brackets E E.These abutments should be provided in such numher as to bear against thebolt-frame at various points. If, now, a charge of dynamite should beexploded against the exterior of the safe, the inward motion of the doorand the bolt-frame would be arrested by these abutments before a strainwould be brought upon the fastening-bolts that hold the bolt-frame.

Fig. 2 is a horizontal section of a portion of a safe having an outerand an inner door, the abutments being arranged between the two. In thisfigure, A is the outer door, and A the inner one. The abutments D D,instead of being fastened rigidly, as in the other case, are arranged toswing up out of the way, in order to permit the inner door of the safeto be opened. The abutment D is shown as in place for resisting theeffect of a shock, while the abutment D is shown as thrown up for givingaccess to the interior of the safe. Of course various other modes ofarranging these supporting abutments will readily present themselves toa person skilled in the art.

What is claimed as new is- 1. The combination of the bolt;fra1ne of asafe or vault door and support-ing-abutments, to prevent the same frombeing detached by the force of a shock directed against the door.

2. In combination with the bolt'frame of a safe or. vault door,supporting-abutments for preventing the frame from being detached by theforce of a shock, but capable of being moved out of the way when thedoor is opened, substantially as and for the-purpose set forth.

HENRY F. NEWBURY.
